Membranes for osmotic processes

Following what Juncal and Mikel wrote about, I’m writing today about membranes used to obtain power from the Osmosis process. As both of my colleagues mentioned, the main restriction of the development of this new technology is the membranes that … Seguir leyendo

Osmotic power by vapour

One of the most problematic causes from preventing a commercial development of osmotic power is membranes which are used in the osmosis process. These membranes have to be replaced periodically, every six months, as Junkal wrote in the last post. … Seguir leyendo

Blue Energy

Introduction: the osmotic process. In the osmotic process two solutions are involved and each of them has its own salt concentration (if the salinity is the same for both it has no sense talking about the osmotic process, as it … Seguir leyendo

Santoña’s wave farm

Last post I wrote about a buoy produced by Ocean Power Technologies, a device that produces electrical energy from the vertical movement of the waves. Well, one of the places that they’ve implemented this innovative system is in Santoña, Cantabria. … Seguir leyendo

WaveRoller. The power of underwater waves

Many years ago, in Finland, Rauno Koivusaari was diving when a door of a wrecked ship nearly hit him. Eureka! It was the beginning of WaveRoller. Until now we have written mainly about sea waves that are on the ocean … Seguir leyendo

On-Shore Power

Up to now, we have been trying to explain the operational principles of several revolutionary devices whose aim was generating electric energy from the motion of waves, but all of them have  one main characteristic: they were offshore machinery, which … Seguir leyendo

Ocean Power’s PowerBuoy

Last post, I talked about a buoy that produces energy with the air that enters it. This time, I am also going to talk about a buoy, but that has a totally different approach of obtaining energy from the waves. … Seguir leyendo
